Icon A5 tail wag fix

So as we all know the parkzone Icon A5 (not the umx version) has a tail wag issue. As I have looked through the internet I tried a mod that actually worked. In installed 2 carbon fiber rods. One parallel to the belly of the plane and the other one parallel to the vertical fin. It took in my opinion about 70% of the tail wag. Usually it doesn't wag anymore except in the 2 following occasions. 1st in high dives after a loop, and2nd going with the wind in relatively strong winds. What both of these have in common is that they allow the prop to windmill because I take power away to avoid going to fast. Many people say that the turbulence caused by the windmilling prop causes the tail wag. My esc has the option a hard, medium, soft break. Since I'm new to setting things up myself I don't know much about this. I set up the medium break. I have tried it yet. So my question is, is medium ok? Or do I need to set a stronger break? And is the break unhealthy for both esc and motor? Thanks for forming part of this conversation. Have a nice day....

If you have any other mod that worked please fell free to share...

tail waggle fix.

ICON A5 with tail Fin Mod. (10 min 2 sec)


Hope this link works for you. This video shows that the tail waggle can be fixed using additional fins on the underside of the horizontal stabiliser. I think the music is of the band "Yes" though I don't know which particular album. Classic seventies prog rock. Anyway, I see no tail waggle when otherwise there definitely would be. The reasoning here is that, when the plane is descending without much throttle, the fin is in a zone of turbulence caused by the rather bulbous cockpit/motor mount, therefore rendering it useless in stabilizing yaw. The extra side fins are outside the zone of turbulence so are effective.
